It is the year 2977 and humanity has stagnated into a quiet monotony. Machines perform all labor, while the populace remains placid through subliminal cues; officials are indolent, indulging only in leisure pursuits such as golf and horse racing. Captain Herlock has shattered this dull mindset, guiding a band of like‑minded insurgents toward a more daring existence aboard the vessel Arcadia.
A shadowy entity called the Mazone has breached Earth, manifesting as enigmatic cloaked women who eliminate anyone who suspects their sinister schemes—Tadashi Daiba is now on their list. After his scientific father was dismissed by authorities and slain by the Mazone, he allies with Captain Herlock and his motley crew of outlaws to help thwart the looming extraterrestrial menace. In a desperate bid to preserve the future of all sentient beings.
